  • disk brakes used in vehicles generally have a structure in which a brake caliper is provided with a pair of caliper side mount portions, while a vehicle body side support portion is provided with a pair of support portion side mount portions, opposed surfaces of the mount portions are set abutting on each other, and fastening bolts are mounted in bolt mount holes formed respectively in the mount portions, whereby the brake caliper is fixed to the vehicle body side support portion.
  • disk brakes of this type there is a disk brake in which a collar member is disposed in portions, on the opposed surface sides, of bolt mount holes in each abutting set of the caliper side mount portion and the support portion side mount portion, in such a manner that the collar member extends from one to the other of the portions, positioning of the brake caliper in the direction along the opposed surfaces is achieved by the collar members, and positioning of the brake caliper in the direction orthogonal to the opposed surfaces is achieved by the mutual abutting of the opposed surfaces (see, for example, Patent Document 1).
  • the tolerance of the interaxial distance of each pair of bolt mount holes is in some cases set to be smaller than the general tolerance, in view of that it is desirable to minimize chattering of the collar members. This is important for preventing the brake caliper from being deviated in the direction orthogonal to the plane of the brake disk, in the radial mount type disk brake in which each of the bolt mount holes is provided in parallel to the radial direction of the brake disk.
  • the present invention aims at providing a brake caliper which makes it possible to efficiently manufacture a brake caliper and a vehicle body side support portion while maintaining accuracies of positioning of the brake caliper.

  • the error can be absorbed by the counterbore formed in an oblong sectional shape, so that the mounting of the brake caliper is not hampered and the positioning accuracy of the brake caliper can be maintained.
  • the brake caliper can be fixed in the state of being accurately positioned relative to the caliper bracket, without requiring a fine adjustment work.
  • the tolerance of the inter-axial distance of the counterbores can be a general tolerance, so that the brake caliper and the vehicle body side support portion can be manufactured efficiently.
